The demand was also revealed to have fallen by two per cent year-on-year when compared to the first quarter of 2023. Demand for gas in electricity generation remained at 39 per cent in Q1 2024 as it did in Q4 2023, while wind energy’s contribution to electricity generation which increased from 42 per cent to 43 per cent over the same period.
Gas Networks Ireland’s Director of Strategy and Regulation, Edwina Nyhan said: "The first three months of the year is testament to how an integrated energy system works in practice, with wind and gas complementing each other to generate, when combined, 82% of Ireland’s electricity demand.
"While wind reached a higher electricity generation peak of 81 per cent1 – one per cent more than gas’s peak contribution - gas remains a more consistent energy source, with contributions to the grid of a minimum of 10 per cent1 in Q1, in comparison to low contributions for wind of less than 1 per cent1 during the same period.

"Gas contributions were particularly strong over the recent Easter weekend2, for example, generating 47 per cent of electricity in comparison to 37 per cent for wind. Looking further back in the quarter, in the month of February, which is traditionally one of the windiest periods of the year, wind energy contributed more to the grid than gas did, in a reversal of what is more often the case.
"During January’s long cold spell, when there was little or no wind blowing across the country, gas stepped up and provided almost all of Ireland’s electricity. However, later that month the gusty conditions during storms Isha and Joceyln, saw wind energy generating 71 and 70 per cent of electricity, respectively."
March saw overall gas demand increase by 5 per cent month-on-month from February but fall 11 per cent year-on-year from March 2023. Gas's contribution to electricity generation fell from 45 per cent to 36 per cent year-on-year and from 37 per cent to 36 per cent month-on-month. Throughout the month, gas accounted for 36 per cent of Ireland's electricity, while wind energy took the lead for the second consecutive month with 46 per cent.
Throughout March, Gas maintained its significance as a backup energy source, consistently contributing no less than 12 per cent to electricity generation and peaking at 73 per cent during critical periods.
In March demand for gas from the air travel sector decreased both month-on-month (-14 per cent) and year-on-year (-17 per cent), while industries such as manufacturing5 (+37 per cent year-on-year; +24 per cent month-on-month) and construction (+14 per cent year-on-year; +6 per cent month-on-month) saw significant increases in gas demand.
Compared to 2023, the transportation sector saw a significant uptick in gas demand, marking a 14% year-on-year rise. Fuelling with compressed natural gas (CNG) can substantially reduce emissions from heavy goods vehicles (HGVs) and with CNG suppliers now sourcing gas via renewable sources, BioCNG can turn a HGV into a carbon neutral vehicle, providing the Irish haulage industry with a clean alternative fuel option.
